Jeremiah 35:11

When the Chaldean army came into the land, they saw there would be no quiet abode for them any where but in some fortified place. The Syrians joined with the Chaldeans in this war, as we read, 2 Kings 24:2. This they tell the prophet was the reason why they, who never used to dwell in cities nor fixed houses, came to dwell at Jerusalem, to prevent being destroyed by the foragers for these armies.
